Ukuqhathanisa Igwebu Le-PU Elingavimbi Umlilo Negwebu Le-PU Elijwayelekile

Igwebu le-fire retardant polyurethane (PU) liya ngokuya liduma ezimbonini ezahlukahlukene ngenxa yekhono layo lokwehlisa ijubane noma ukuvimbela ukubhebhetheka kwemililo. Lolu hlobo lwegwebu luphathwa ngezithasiselo ezenza lumelane namalangabi namazinga okushisa aphezulu, okwenza kube inketho ephephile ukusetshenziswa ezakhiweni, ifenisha, kanye nezicelo zezimoto. Kulesi sihloko, sizoqhathanisa igwebu le-PU elivimbela umlilo negwebu elijwayelekile le-PU, sidingida umehluko ekubunjweni kwawo, izakhiwo, kanye nezicelo.

Ukwakhiwa kwe-PU Foam ebuyisela umlilo

Igwebu le-PU elivimbela umlilo lakhiwe izingxenye ezifanayo eziyisisekelo njengegwebu le-PU elivamile, okuhlanganisa i-polyol, i-isocyanate, nezinye izithasiselo. Umehluko oyinhloko usezithasiselweni ezisetshenziswa ku-PU Foam evimbela umlilo, eklanyelwe ukusabela lapho evezwe ukushisa noma amalangabi, akhiqize ungqimba lwe-char oluvikela igwebu futhi luvimbele ukuthi lingabambi umlilo. Lezi zithako zingabandakanya i-phosphorus, i-nitrogen, noma i-halogen-containing compounds esiza ukunciphisa ukuvutha kwegwebu.

Ukuba khona kwalezi zithako kungashintsha izakhiwo ezingokomzimba nezamakhemikhali zegwebu le-PU, kuthinte ukuminyana, ukuguquguquka, nokuqina. Igwebu le-PU elivimbela umlilo lingase libe nokuminyana okuphezulu kancane kunegwebu le-PU elivamile ukuze lifake izithasiselo ezingashi ngaphandle kokuphazamisa ukusebenza kwegwebu sekukonke.

Izakhiwo ze-PU Foam Engavimbeli Umlilo

Enye yezinto eziyinhloko ezibeka igwebu le-PU elivimbela umlilo ngaphandle kwegwebu elijwayelekile le-PU ukumelana kwayo namalangabi namazinga okushisa aphezulu. Igwebu le-PU elivimbela umlilo lihlolwa ngokwezindinganiso zomkhakha ukuze kuqinisekiswe ukuthi lihlangabezana nemibandela ethile yokuvutha, ukuphehla intuthu, kanye nobuthi. Lolu hlobo lwegwebu ngokuvamile luzicisha ngokwalo, okusho ukuthi luzoyeka ukuvutha uma ilangabi selisusiwe, okunciphisa ingozi yokubhebhetheka komlilo.

Ngaphezu kwezakhiwo zayo ezikwazi ukumelana nomlilo, igwebu le-PU elivimbela umlilo liphinde linikeze ukwahlukanisa okuhle kokushisa, ukumuncwa komsindo, nezici zokumisa. Ingasetshenziswa kuzinhlelo zokusebenza ezihlukahlukene lapho ukuphepha komlilo kukhathaza khona, njengokwakhiwa kwezakhiwo, izimoto zokuhamba, kanye nefenisha. Igwebu le-PU elivimbela umlilo litholakala ngamabanga namafomu ahlukene ukuze livumelane nezidingo ezihlukahlukene, kusukela kumaphaneli okufaka izinto aqinile kuya kumakhushini okuhlala avumelana nezimo.

Izicelo ze-Fire Retardant PU Foam

I-PU Foam ye-Fire retardant isetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza lapho ukuphepha komlilo kubaluleke kakhulu. Embonini yezokwakha, ivame ukusetshenziswa njenge-insulation ezindongeni, ophahleni, naphansi ukuze kusize ukuvimbela ukubhebhetheka kwemililo ezakhiweni. Igwebu le-PU elivimbela umlilo lingatholakala nakufenisha, kumatilasi, nasezindaweni zokugqoka ukuze kuhlangatshezwane nemithetho yokuvutha nokuvikela abathengi ezingozini zomlilo.

Emkhakheni wezimoto, igwebu le-PU elicisha umlilo lisetshenziswa ngaphakathi kwezimoto, ezindaweni zokuhlala, nasezindlini zenjini ukuze kuhambisane nezindinganiso zokuphepha futhi kuncishiswe ubungozi bomlilo uma kwenzeka kuba nezingozi. Imboni ye-aerospace iphinde ithembele kugwebu le-PU elingashisi umlilo ngenxa yezakhiwo zayo ezingasindi, ezikwazi ukumelana nomlilo ezindaweni zangaphakathi zendiza, amaphaneli, kanye nokwahlukanisa.

Ukuqhathanisa ne-Standard PU Foam

Uma kuqhathaniswa negwebu le-PU elijwayelekile, igwebu le-PU elivimbela umlilo linikeza isendlalelo esengeziwe sokuvikela emlilweni namazinga okushisa aphezulu. Igwebu le-PU elijwayelekile aliklanyelwe ukumelana namalangabi futhi lingavutha kalula uma lichayeke ekushiseni, okulenze lingalungeli kakhulu izinhlelo zokusebenza lapho ukuphepha komlilo kuwukukhathazeka. Igwebu le-PU elivimbela umlilo lihlinzeka ngenye indlela ephephile ukuze isetshenziswe ezindaweni lapho ingozi yomlilo iphezulu, njengasezindlini zomphakathi, izibhedlela, nezikole.

Nakuba igwebu le-PU elivamile libiza kakhulu futhi lisetshenziswa kabanzi ezimbonini ezihlukahlukene, igwebu le-PU elivimbela umlilo linikeza izinga eliphakeme lokuvikela umlilo nokuthula kwengqondo. Izindleko ezengeziwe zegwebu le-PU elicisha umlilo zifakazelwa ikhono layo lokuvimbela imililo ukuthi ingasakazeki ngokushesha futhi ibangele umonakalo omkhulu empahleni nasezimpilweni.

Isiphetho

Sengiphetha, i-PU Foam ye-firetardant iyinto ehlukahlukene futhi enokwethenjelwa ebalulekile ekuqinisekiseni ukuphepha komlilo ezinhlelweni ezahlukene. Ukwakheka kwayo okuyingqayizivele kanye nezakhiwo kuyenza ibe ukukhetha okuncanyelwayo ukusetshenziswa ezakhiweni, ifenisha, izimoto, neminye imikhiqizo lapho ukumelana nomlilo kubalulekile. Ngokuqhathanisa igwebu le-PU elicisha umlilo negwebu le-PU elijwayelekile, singabona izinzuzo ezibalulekile ezinikezwa ngaphambili mayelana nokuvikela umlilo nokuthula kwengqondo. Kungakhathaliseki ukuthi elokuhlala, ukuhweba, noma ukusetshenziswa kwezimboni, igwebu le-PU elicisha umlilo liwutshalomali olubalulekile ekuvikeleni usongo lomlilo olungalindelekile.
